Blockit AI
Blockit AI is a San Francisco startup building an AI scheduling agent that runs your calendar for you. You cc it on an email or ping it in Slack, and it books, reschedules, and negotiates meetings autonomously - learning which meetings are movable and which are not. When two Blockit users need to meet, their agents talk to each other directly, skipping the human back-and-forth. Founded by former Sequoia partner Kais Khimji and calendar veteran John Han, the company raised a $5M seed round led by Sequoia in January 2026 and says it has coordinated more than 100,000 meetings across 200+ companies.
Wispr Flow
Wispr Flow is a San Francisco-based AI voice dictation platform that converts natural speech into polished, formatted text across any application at roughly 220 words per minute - about 4x faster than typing. Built by two Stanford AI researchers, the company has quietly become the voice layer that 270 Fortune 500 companies rely on, combining a 10% word error rate (vs. 27% for OpenAI Whisper), 100+ language support, and context-aware formatting that automatically adjusts tone and style based on the active app. With $81M raised and a $700M valuation as of late 2025, Wispr Flow is racing to become the default voice-first operating system for a billion users.
